I just wanted to point out that midnight is supported at both ends -- the start of the day as 00:00:00, and the end of the day as 24:00:00. Perhaps the application software is not distinguishing these?
Modifying Tom's example to insert one more row, you will see:
f1
----------
00:00:00
01:00:00
02:00:00
23:00:00
23:25:59
24:00:00
(6 rows)
I know there are some who require this behavior. (I had to add it to a database product years ago when it was used to develop an application for fire departments.)
